Have A Progressbar When Loading A Form?
Jun 8, 2011
I have a form let's call it Form1 that calls another form(Form2) Form2 to has a bit a code that needs to load in the LOAD_EVENT and takes about 4 seconds.
I have made a new form(frmProgress) that only has a progress bar.I want frmProgress to show up and load the progress bar meanwhile Form2 is loading.I've tried using BackgroundWorker but I can't seem to get the grasp of it.

i have me a database (.sdf) which loads its records into a listview. One of the database, due its size, takes some time before everything is loaded. I'm using cursor.wait atm, but it I guess there's a more professional approach.
How do I show a progressbar while loading the data?
Here's a small piece of the code I use to load the data:

I am trying to use a progressbar to show on main form and then finish when next form is loaded, I have got this code.
1. When I click on button, it must open next form, but the next form must only open when the data in my list box has been loaded from Access Databse. When I run my program, it only shows the progressbar and don't open the next form.
Main form code:
Public Class Main
Dim PB As ProgressBar
Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
[CODE]............................

If I insert in a Form a progressBar (Max value 1000) and I write this very simple example
For x = 0 To 990 Step 10
ProgressBar1.Value = x
Threading.Thread.Sleep(5)
Next
Me.Close
If I run the code with Windows7 setted as Windows Classic I can see the progress bar value go to the max value and after few time the Form Closes (same with Windows XP).But If I run the program with Windows7 setted as Windows7 Basic the progress bar value ONLY goes to the HALF max value and after half time the form Closes.
The code is the SAME, the PC is the same, Seven is the same (only personalized with different theme) but under Windows7 Basic it seems that For x = 0 To 990 Step 10 becomes For x = 0 To 550 Step 10..The INCREDIBLE thing is that if I insert in the For... Next a row like:
Debug.Print(ProgressBar1.Value.ToString)I obtain right values until 990... but for my eyes the progress bar only goes to half value in half time, then the Form closes.

I need to be able to access a progressbar in my form from a separate class.
I tried
Dim Prog as Progressbar
Public Property Pg()
Get
[Code].....
I need to be able to access a control from a separate thread and return to the thread again.
Edit: Its just an example I gave prog a value of the object from the form and the invoke required is put in a sub so thats not my problem.

When a user clicks on Download button on a form,
(1) User should be able to see progressbar form in continuous/marquee style.
(2) When one task is completed, title on the prog.bar form is changed
(3) when final task is completed, progressbar should go away.
What my architect wants: [Code] Downloaddata.vb class, that will actually do the work,and will implement the interface. So DoMyWork(dim frm as ProgressBarForm) implements Iwork.BeginWork.
Twice, it will report the stauts back to progress bar form. ProgressBarForm.vb class(it has BGWorker Thread) will have one public method(name ShowMyProgress) that Downloaddata class can call from its DoMyWork method when status is changed. And also implementation of all 3 events of worker thread.
My Questions:
1. Where should I put BGWorker.RunWorkerAsync
2. What kind of logic should go in ShowProgress method in progressbar and also in DoWork event?
Do I need application.doevents? In nutshell, how Progressbarform and DownloadData will communicate back & forth?

I recently finish my Microsoft VB.net training and learning something about delegates. I have two delegates in a excel source to control a progressbar and a text box on the mainform
Public Delegate Sub ReportProgres(ByVal percent As Integer)
Public Delegate Sub ReportText(ByVal Mytxt As String)
I want to use these delegates in a second excel source also. It gives declared in the first excel file and two conflict errors in namespace windows application.

Is there a way to turn off all visual updates to a .NET form while I am manipulating it? When my program first loads, for example, I set the tab control to the tab that was last open. The user can see the program switching tabs.
I have looked into SuspendLayout and ResumeLayout, but either I don't understand what they are doing, or I am not using them correctly, because they don't seem to have any effect. Someone told me that there used to be a way to turn off paint events in VB 6. Does this still exist in .NET?

I have 2 forms. When a user clicks something on form1, form2 pops up. After user is done with form2 and closes it (where the dataset is updated), I want form1 to "reload" the dataset to reflect changes made in form2.

How do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate ? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :
Private Sub openOrderWindow()
Dim OrderWindow As Orders = New Orders
OrderWindow.ShowDialog()
End Sub
[code]....
I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize itis there any way to make it Movable while it loads?

Does anyone know of anyway that it would be possible to speed up the process of loading forms.With VB6, forms (simple ones) was extremely fast but with VB.net, the initial loading of a form (even the simplest one) takes very long. Although it gets better once it's loaded once and the reloaded the next time (almost instanttaneous), but the first time loading gives a bad impression to any user that .net is actually much slower.

I've got 2 forms; form1 and form2.
Button1 is added to form1.
When I click button1, I want to close form1 and open form2.
I tried the following.
me.close
form2.show
Its not working. Form1 gets closed but form2 is not showing up.
When I use the following code
me.hide
form2.show, its working.
But hide will not unload form1 and it will still occupy memory.
